Hello there, I'm trying out this script and it seems to be awesome! But I'm finding a problem sending HTML messages. Not sure if I need to include tags like <HTML><HEAD><BODY>.I tested both ways and none worked for me, I was trying to send an image (I inserted the full URL for this image), but all I got was the text in yellow color (it was supposed to be white) and no image at all I really need the image to be sent, that's the most important thing on this newsletter... any ideas?

There have been some reports of people having problems sending HTML messages, and the cause hasn't really been identified. I would say to make sure that you are including all of the tags (including <HTML> and <BODY>).
